CUTTER BAR.

SPECIFICATION forming part of Letters Eatent No. 468,583, dated February 9, 1892.

Application filed July 28, 1891. Serial No, 400,963. (No model.)

To aZZ 1072 0721, it may concern:

Be it known that I, WILLIAM SHERMANSUT- TON, a citizen of the United States, residing at Bluff Point, in the county of Jay and State of- Indiana, have invented certain new and useful Improvements in G utter-Bars; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

My invention relates to improvements in cutter-bars adapted for use in harvesters, mowers, and reapers,and one object of my invention is the provision of a cutter-bar which will retain the knives or cutters firmlyin position, and which will permit them to be quickly removed when found necessary.

Another object of my invention is the provision of a cutter-bar which will comprise few parts, whereby the same is rendered strong and durable and will withstand the hard usage to which it is subjected.

Another object of my invention is the provision of a cutter-bar which will be thoroughly efficient in operation and which can be produced at a low price, thereby possessing all the features of merit desired in a device of this character.

To attain the desired objects my invention consists of a cutter-bar embodying the novel features of construction and combination of parts, substantially as herein illustrated, described, and specifically defined by the claims.

Figure 1 represents a perspective view of a cutter-bar embodying my invention. Fig. 2 represents a vertical longitudinal section thereof, the teeth being confined or retained in place by the fastening. Fig. 3 represents a similar view, on an enlarged scale, of a portion of the bar, the fastening or latch being released to allow the removal of the cutters; and Fig. 4 represents a transverse section through the bar and cutters.

My improved cutter-bar consists of the two strips or bars A A, formed each with a groove B in its inner face, which, when the strips are secured together, forms a channel (1, in which the enlarged inner edge D of the cutters E rests, and by this peculiar construcremoved when necessary by sliding them out,

as is evident from Fig. 3. To the top of the bar at the inner end I secure the plate F, which is bifurcated and formed with the eyes or loops G, in which fits the bent lower end of the pitman H, and in the lower strip of the bar is made a kerf J, in which is pivoted one end of the an gleshaped fastening K, the other end whereof passes into or rests between the eyes G and is secured by the bend on the pitman, the fastening having a lugL on the upper end to prevent it from displacement. By this construction it will be seen that the cutters can be readily secured and retained in position in the bar and can be easily removed when it is found necessary, and to secure the cutters at the outer end Iemploy a block M, which is rigidly secured in place in the channel of the bar. It will thus be seen that: I provide a cutter-bar which is of simple, strong, and durable construction, which is thoroughly efficient in operation, which will permit of ready and easy removal and replacement of the cutters, and which can be produced at a low price.

I claim as my invention- 1. A cutter-bar consisting of two strips or bars having an interior channel between its upper and lower faces and a longitudinal slot in its front face, communicating with the channel, said slot being of less height than the channel, cutters or teeth having enlargements fitting in said channel, whereby they are held from movement except longitudinally of the cutter-bar, a pivoted latch or fastening at one end of the bar, and a pitman having one end engaging and retaining said latch, substantially as described.

2. A cutter-bar having an interior channel between its upper and lower faces and a longitudinal slot inits front face, communicating with the channel, said slot being of less height than the channel, cutters or teeth having enlargements fitting in said channel, whereby they are held from movement except longitudinally of the cutter-bar, a plate carried by said bar formed with eyes, a fastening having one end pivoted to the bar and the other end normally arranged between the eyes, and a pitman having one end fitting in the bar and having a lug on the free end thereof, and a pitman having one end engaging the free end of the fastening adjacent to the lug thereof for retaining the fastening, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
